Terrific quality and a breeze to assemble.

Marco Cooper
Great Locking Box

Better than expected !!!!

William Myers
A Solid and Practical Mailbox

Straight forward installation with good instructions. I used a treated 4X4 attached to the post and cemented it in for a rock-solid feel. After several months in the weather it still looks great. It can hold several days of mail. Small packages such as boxes of checks fit the opening easily. My two immediate neighbors and I are very satisfied with this purchase.

Michael Grant
Triple Box Install

Good quality…easy order and delivery experience. Product easy to assemble. Sent wrong color spreader bar in initial shipment, but customer service sent replacement part fast and made returning the incorrect item easy.

Hi Mr. Grant,

Please accept our apologies for the mix-up with the spreader bar, and thank you for your feedback.

Kind regards,
